Absorption of its hetero-organization such as bone and venous blood to light is invariable.Shone when with constant light λ 1, the λ 2 of two kinds of specific wavelengths
When shooter refers to, if suitably selection lambda1-wavelength λ 1 absorption characteristics, i.e., about 805nm such as (Hb02, Hb) having here, utilization
The Lambert-Bear laws and approximate formula that can release arterial oxygen saturation according to the definition of oxygen saturation is：Sa02=a
In bQ formulas：Q is that the ratio between the absorbance change of two kinds of wavelength (Hb02, Hb) a, b are constant, with Instrument sensor structure, measurement bar
Part is relevant.Focus on to biological tissue be an anisotropy, strong scattering, weak absorbing complicated optical medium, therefore it is actual survey
It can not be described in amount with a strict formula, so generally by the ratio between measurement dual-beam absorbance change, Ran Houtong
Cross empirical calibration curve and finally obtain oxygen saturation.And when selecting dual-beam wavelength, it is typically chosen a length of 660nm of incident light wave
And 940nm.
In the specific implementation, blood oxygen transducer can be largely classified into fingerstall type, ear-lobe type, coated and adhesion by profile
Type, can be divided into adult type by purposes and child form, infantilism are several again.No matter profile and type, the original of blood oxygen transducer
It is the same that reason, which is constituted, and they are by luminescent device (photoemission diode) and receiving device (photoelectric receiving diode) group
Into.It by wavelength is that 660nm (650nm) feux rouges and wavelength are 940nm (910nm) infrared light emission pipe group that luminescent device, which is,
Into.Photoreceptor is mostly big using receiving area, and sensitivity is high, and dark current is small, the low PIN-type photodiode of noise,
The incident optical signal received is converted into electric signal by it.
In the present embodiment, if the product form of oximetry sensors is fingerstall, fixes two in fingerstall upper wall and put side by side
The light emitting diode (photoemission diode) put, emission wavelength is respectively 660nm feux rouges and 940nm infrared lights.Lower wall is one
Individual photoreceptor (photoelectric receiving diode), the feux rouges and infrared light that it will transmit through finger is converted into electric signal.Blood oxygen
During meter operation, timesharing drive circuit is allowed two light emitting diodes by certain time interval and sent out respectively with relatively low dutycycle
Light, the strong and weak ratio of the transmitted light received according to optical diode luminous intensity and photoelectric tube can calculate whole blood absorption rate respectively
A660 and a940, then in conjunction with the coefficient A and B of experimental calibration, is substituted into aforementioned formula, it is possible to calculate blood oxygen saturation number
It is worth.
